Raft (pairs) all the resistors R1, R2, and R3 as shown below on the PCB or breadboard (project board), Connect the adapter or 15 Volt DC power supply, then set up the measuring instrument (multimeter). Turn on the power supply selector on the multimeter set to be in a position volt meter with the correct scale. Setting the wrong scale on analog multimeter can damage the gauge because the needle will move too cepat.Ukur voltage at R2 where the probe (+) attached to R2 foot closest to the positive voltage source and the probe (-) should be placed at the feet R2 The closest predictably negative voltage source. If using analog multimeter, this condition should not be reversed because it can cause damage to the measuring instrument. See the measurement results indicated by the pointer or the displaydigit numbers if using a digital multimeter. Record the results and compare with the results of the calculation.
